A Sean McConville double helped Accrington come from 2-0 down to beat Port Vale 3-2 and remain third in the Sky Bet League Two table.Port Vale opened the scoring in the third minute when David Worrall played a ball in from the right and Tom Pope headed home his 15th goal of the campaign.Vale doubled their lead after 41 minutes when Michael Tonge's free-kick from the edge of the area went through a sea of bodies and into the bottom corner of Aaron Chapman's goal.Stanley got a goal back on 51 minutes when Billy Kee flicked the ball back for McConville and the winger belted it into the net from 10 yards.Kee scored a controversial equaliser three minutes later from within the six yard box after Kayden Jackson's initial strike was blocked - Vale felt Kee handled the ball over the line but it was given and the striker celebrated his sixth goal in six games.Vale should have been in front but for a superb save from a Tom Anderson header which Chapman touched onto the bar after 66 minutes.McConville made them pay in the 72nd minute with a fierce strike after Kee once again set him up.
